Abstract
The invention relates to a method for operating a braking system for motor vehicles with electrically actuated hydraulic valves, the coils of which are powered up, at least in phases, with currents which modify the currentless state of the hydraulic valves, in order to heat the hydraulic fluid present in the system. The hydraulic fluid is heated via a heating profile which, in accordance with the hydraulic fluid temperature, activates the heating phase of the hydraulic fluid. The heating profile consists of a first heating phase and, subsequent thereto, a second heating phase. During the first heating phase, the coils are powered up in such a way that the coil temperature at the end of the first heating phase corresponds to a pre-defined temperature value of the coil which is at least approximately maintained during the second heating phase when powering up the coils.
